Which are the good blockchains?

There’s literally thousands of blockchains. Anyone with developer skills can create one pretty easily. This page is just my personal views on the most relevant, most talked about blockchains that I come across regularly.

Disagree? Good stuff, there’s lots of different views in this space. The basis for the views I use on this page are good blockchains in the sense of:

  • Blockchains with a purpose of bringing decentralised services and value to everyone for the long term.
  • Blockchains that are well decentralized. I.e. controlled by their community, not by their founders or powerful stakeholders.
  • The best blockchains are not ones whose coins are bought by venture capital funds, but those that have the potential to remain decentralized and change the worlds financial and governance systems.
  • Blockchains that for all the above reasons stand a good chance of doing really well in the longer term.

The good blockchains


OK, Cardano is my favoured blockchain so I have a natural bias towards it.  However it’s my favourite good blockchain because:

  • The most passionate, here for all the right reasons and a large community of any blockchain I’ve come across.
  • 90%+ of $ADA is held by retail users.
  • The most decentralized blockchain, by some margin. Operated by thousands of stakepools, most owned and controlled by individual community members.
  • Designed right, the most academically researched and built right from the ground up blockchain of them all.
  • Reasonable transaction fees to ensure the blockchain can fund itself over the long term and the best plan being executed to achieve full chain-based governance.
  • Completely open source.











The somewhere in between blockchains


As a secure store of value, widely respected and well adopted blockchain Bitcoin is number 1. For now.

It’s downsides:

  • Its environmental credentials are absolutly awful. There is no need for its Proof of Work (PoW) approach today, yet it has no plans to move away from it.
  • It doesn’t do anything other than store/transfer of value (no smart contract capability or ability to store other digital assets in a useful way).


A commercial coin blockchain. Intentions are good as I understand it.

It’s downsides:

  • Apparently a really confusing blockchain and community, tech not user-friendly.

The bad blockchains

Friends don’t let friends buy coins on pump-and-dump blockchains. DYOR, don’t fall for the lies, smoke and mirrors and blatant price manipulation tactics.
Don’t be exit liquidity for the big coin holders when the time comes.


Created to make its founders rich.

Has an unlimited supply with 90% of the current supply being held by companies like FTX & Alameda.

Has suffered regular and frequent outages and security vulnerabilities.
